1. Introduction
The GK-604D is made up of three components:
•the Readout Unit, consisting of a hand-held field PC running the GK-604D
Inclinometer Readout Application (see Figures 1 and 3).
•the GK-604D Remote Module, housed in a weather-proof reel enclosure containing
the cable that directly connects to the inclinometer probe (see Figures 1 and 6)
•The inclinometer probe, either analog or digital. See Figure 1 (digital, 6100D-X) and
Figure 4 (analog, 6100-1X).
Figure 1 – Model GK-604D, Digital Inclinometer System
The Readout Unit and Remote Module components communicate wirelessly using
Bluetooth®, a reliable digital communications solution. This simplifies the handling of the
system in the field as well as simplifying the transfer of data to your PC workstation for
final analysis.
1.1 Features
Rugged, general purpose, reliable readout based on a hand-held PC:
•all the benefits of a Windows Mobile compatible device (Windows file system,
RS-232, USB and wireless connectivity)
•long battery life
•ease of use

2
Lightweight and simple Remote Module:
•lithium battery (8 + hours of continuous use)
•one button operation; automatic power down when Bluetooth connection is
dropped or after several minutes of inactivity
•rugged
•reliable connection to standard inclinometer probes (Figures 1 and 4) is
accomplished via model 6000-2 control cable which features a lightweight,
polyurethane jacket and is less than 7 mm in diameter (see Figure 2). The
control cable contains a central Kevlar®strand with a breaking strength of 150
kg

1.2 GK-604D Inclinometer Readout Application
The GK-604D Inclinometer Readout Application (GK-604D IRA) installs and runs on
a ruggedized hand-held PC (FPC-1) (see Figure 3) and is designed to communicate
via Bluetooth with Remote Modules connected to analog or digital probes (see
Figure 4), both MEMS and force-balance type. For digital probes the Remote
Module is fully contained within the reel as depicted by Figure 1.
For analog probes an interface unit, GK-604-4 (see Figure 5), connects directly to
the probe (analog MEMS and force-balance type) and can be purchased as a
separate unit or as part of the GK-604-3 reel system (see Figure 6).

Note: The GK-604D Inclinometer Readout Application will also operate on the
Archer Field PC from Juniper Systems (shown in Figure 6) as well as the newer
Archer2.
1.2.1 Tiltmeter and Compass Probes
In addition to standard inclinometer probes, the GK-604D IRA also can be used
with Geokon Tiltmeter and Compass Probes. See Appendices G and H for more
information on these probe types.

1.3Before using the GK-604D Inclinometer Readout
The readout software runs as an application under Windows Mobile 6 operating
system installed on a hand-held PC (FPC-1).
•The user should familiarize themselves with the FPC-1 and the Windows Mobile
OS.
•It is assumed in the instructions below that the user can launch applications
from the Start button including File Explorer and the Bluetooth Settings
manager.
•It is assumed that the user can tap the keyboard icon as needed and use the on-
screen keyboard to enter text and numbers.

2. Installation and Operation
The steps described in section 2.1 are an attempt to guide the user through the process
of launching the GK-604D IRA, connecting to the probe and taking a survey. If all parts
of the GK-604D are purchased as a system, Geokon makes every effort to ensure that
the system is completely set up and working before it leaves the factory. Other times,
the user may already own the hand-held PC and are setting up their hardware and
software for the very first time. The steps below attempt to cover all cases and refer the
user to the appropriate section when more information is needed.
For those users that have purchased a complete GK-604D system, a workspace with the
name of “GK604D” and a probe library called “ProbeLibrary” will have been pre-defined
and the FPC-1 unit will already be paired with the Remote Module. Note that the
workspace and probe library names can be changed at any time or new ones can be
created (see section 3.2.1). When purchasing a GK-604D system, sections 2.2 through
2.4 can possibly be skipped but a quick review is recommended.
NOTE: Always make sure that the inclinometer probe is attached to the reel before
attempting the quick start sequence below.
2.1 Initial Quick Start Sequence
The following steps are a guide to the typical operation of the GK-604D and, if
followed, should result in a successful “hole” survey being taken:
A) If the Remote Module was purchased separately from the FPC-1 unit or if a new
Bluetooth pairing is needed, see section 2.2 (Establishing Contact with the
Remote Module).
B) Launch the GK-604D IRA by tapping on “Start” from the FPC-1 main
window, tap “Programs”, then tap the GK-604D IRA icon. If the
GK-604D Inclinometer Readout Application has not been installed,
please see section 2.3 (Installing the GK-604D IRA).
C) If the window shown in Figure 18 is displayed instead of the Main Window (see
Figure 25), please refer to section 2.4, “Starting the Inclinometer Readout the
First Time”.
D) If the Inclinometer System is an analog system (probe model numbers 6100-1E
and 6100-1M) then a “probe” must be defined in the Project Explorer Probe
Library (see section 3.2 and 4.2 for more information regarding adding and
configuring a new probe). After adding a new analog probe configuration, skip to
step F.

8
E) If the Inclinometer System is a digital system (probe model numbers 6100D-E
and 6100D-M), any new “probe” will be discovered upon connection to the
Remote Module (covered in later steps).
F) If launching the GK-604 IRA for the first time, a “project” and a “hole” must be
defined before connecting to the Remote Module (see sections 3.2, 4.4 and 4.1
for more information regarding adding and configuring Project Explorer
elements).
NOTE: If preparing to connect to a digital system the first time, please select
“UNKNOWN” for the hole parameter, “Probe Name:”.
G) If it’s not selected already, select the new hole (by tapping on the hole icon in
the Project Explorer) created in step F. Press the button labeled “POWER ON
(BLUETOOTH)” on the Remote Module. A blue light should come on and start to
blink, signifying that the Remote Module is waiting to connect to the FPC-1 unit.
H) To start the connection process, tap on the Application Menu (see section 3.3)
then tap “Live Readings”. By default the application will look for a Bluetooth
connection on “COM5”. If the Remote Module fails to connect with the FPC-1,
then the window shown in Figure 28 will be displayed, indicating that either the
Remote Module is no longer trying to connect (timed out) or that the Bluetooth
pairing is associated with another COM port. Make sure that the proper COM
port is selected and tap “Reconnect”.
If connecting to an analog system, after a few seconds, the blue light on the
Remote Module should change to a steady state blue (lit but not flashing) and
the Live Readings Window will be displayed (see Figure 29). Skip to step I.
If connecting to an digital system, after few seconds, the blue light on the
Remote Module should change to a steady state blue (lit but not flashing) and
one of two windows will be displayed:
a. If the window shown in Figure 7 is displayed, then the probe has not
been previously detected by the GK-604 IRA (digital systems only). In
this case, tap “ok” and the probe will be added to the Probe Library and
the window shown in Figure 8 will be displayed. This allows an
opportunity to give the new newly detected probe a user friendly name
and description. See section 4.2, Probe Configuration for more
information on probe settings. When satisfied with the settings, tap
“Menu->Save Settings” to exit the Probe Settings Window (see Figure 8).
If the probe name was set to “UNKNOWN” in step F, the window in figure
9 will be displayed, allowing the name of the probe just found to be
saved into the current hole configuration.
